Perfume in the great monotheistic faiths
With Constantine’s adoption of Christianity in 4 AD, the immoderate use of perfume, associated with Eastern religions such as the cult of Isis, began to dwindle. When the Roman Empire collapsed, the Catholic Church remained the only organised power confronting the Barbarians and the use of perfume was restricted for many years.
Jewish religion and culture developed under both Eastern and Egyptian influences. It is therefore hardly surprising that, once more, perfume was primarily used for sacred rituals. Early Jewish texts exemplify the predominance of religion in the use of perfumes and incense.
For Muslims, perfume played a central role in all religious ceremonies, and the Koran specified which products to use and which rituals to follow for every circumstance. Secular use was also widespread and Arab scientists contributed their knowledge to perfumery with the development of the first tin-plated copper still (the previous stills were made of glass), associated with a glass cooling coil. As trade with the rest of the civilised world spread rapidly, so did their skills in alchemy.
